Pyruvate Kinase M2 Mediates Apigenin‐Induced Energy Crisis and Apoptosis in Colon Cancer Cells
Food Frontiers, Volume 7, Issue 4, July 2026.Apigenin, a dietary flavonoid with low toxicity, induces profound bioenergetic collapse in colon cancer cells by downregulating PKM2. This metabolic crisis, characterized by suppressed glycolysis and mitochondrial dysfunction, ultimately triggers robust apoptosis.
